摘要
目的有大量证据揭示,非酒精性脂肪性肝病患者是心血管疾病的高危人群,而心血管疾病是此类患者死亡的首要原因。本研究旨在评价黑孜然对肝脏和心血管保护作用。方法采用PRISMA指南进行荟萃分析,于2022年6月在PubMed、ScienceDirect、Cochrane Library网站分别检索2010年1月至2021年12月发表的相关文献。应用Review Manager软件(5.3版)对天冬氨酸转氨酶和丙氨酸转氨酶水平、血脂、血糖、体重和体重指数等指标进行统计学分析。结果黑孜然能显著降低研究对象的天冬氨酸转氨酶(P=0.009)和丙氨酸转氨酶(P<0.05)水平。同时,黑孜然组受试者脂肪肝治愈率显著高于安慰剂组(P=0.0001)。此外,黑孜然组受试者的血脂、血压、空腹血糖均显著降低(P<0.05)。然而,黑孜然组与安慰剂组的体重和体重指数无显著差异(P>0.05)。结论尽管黑孜然组和安慰剂组的体重和体重指数差异不显著,但黑孜然对非酒精性脂肪性肝病或慢性肝病患者确实具有一定的肝脏保护和心血管保护作用。
Objective A significant amount of evidence has lately revealed that individuals with nonalcoholic fatty liver diseases(NAFLD)are at high risk of cardiovascular diseases,which is the primary cause of death in patients.This study is to evaluate liver-and cardiovascular-protectant effects of Nigella sativa(N.sativa).Methods The meta-analysis was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines.The literature review was conducted in June 2022 with papers retrieved from the PubMed,ScienceDirect,and Cochrane Library websites from January 2010 to December 2021.The Review Manager version 5.3 was applied for the statistical analysis of parameters like aspartate transaminase(AST)and alanine transaminase(ALT)levels,lipid profil,blood glucose level,weight,and body mass index(BMI).Results The results showed that N.sativa could significantly decrease the AST(P=0.009)and ALT(P<0.05)levels in research subjects.Subjects in the N.sativa group had a significant higher cure rate of fatty liver than those in the placebo group(P=0.0001).In addition,lipid profile,blood pressure,and fasting blood glucose of subjects all significantly reduced in the N.sativa group(P<0.05).However,the comparison of body weight and BMI between the N.sativa group and placebo group did not show significant difference(P>0.05).Conclusion N.sativa did have certain liver-protectant and cardiovascular-protectant effects on patients with NAFLD or chronic liver diseases(CLD),despite the insignificant comparison of body weight and BMI between the N.sativa group and the placebo group.
